Work has continued at a feverish pitch this week at TwinSpark Central! The rear trailing arms in steel put up too many fitment issues and we decided to pick up the project again after the first races next weekend. Woodstock’s got its engine back in and should be barking at the neighbors soon again. The guys did a terrific job fitting lightweight windows all around and this means we are starting the season some 15 kilo’s lighter than we ended last year’s.

The Hulk sports our RSR brakes in the front now, but due to lack of time it still has the alloy trailing arms and the Long Distance rear calipers on. Engine goes in tomorrow.

Both cars are off to our friends at Beek Racing in The Hague on Tuesday to be lowered, corner weighted and aligned. Both cars need to be set up to take advantage of the slicks we run on, which [...]

TwinSpark friend and GT3 enthusiast Ivo van Riet has organized a Porsche only track day on June 23 2012 at the venerable racing venue of Zandvoort. Registration fees are Euro 450 per car for the day. It’s a two class event, where we expect to see a gaggle of 911’s from all generations between race-experienced rivers and Club drivers. Although the sound constraints seem severe, they are on a drive by basis in only one spot of the track, coming out of the corner into the straightaway. A rapid short shift to the next gear will keep you out of trouble!

Ivo has offered a free pit box to groups which bring 4-5 cars to the event, an offer worth Euro 150 a day. We like the date, as it is on a Saturday, normally a feature which comes at a premium. Grab this outstanding opportunity to discover the undulations and technical corners of this [...]

Having your classic 911 sit on its wheels in a well-balanced manner makes an incredible difference in its road behavior. Sounds like it makes perfect sense, right? You’d be surprised what we find has been done to guests at the TwinSpark Racing Lair!

To be able to fit short, RSR or Turbo trailing arms (no, they are not the same…), a modification to the non-RSR (who owns a real one these days?) non-Turbo tub needs to be performed. The pick up points for the rear trailing arms need to be raised and moved sideways. This allows the short trailing arms to provide a sturdier stance to your car.

Sounds easy, but to get this cut and weld job done accurately, a special rig is needed to simulate the set up of the rear suspension. A few year ago we found out that we couldn’t drop our 1973 RSR (originally a 1973 [...]
